13-17
Pre-postheating control
The pre-postheating function is controlled by the preheating unit.
OPERATING PRINCIPLE FOR PRE-POST HEATING
1) "Preheating" on ignition
a) Variable preheating
The warning light lighting time and the
supply to heater plugs time depends on the
coolant temperature and the battery
voltage.
In all cases the injection warning light
lighting time cannot exceed 15 seconds.
b) Fixed preheating
After the warning light goes out the plugs
remain supplied for a fixed period of
10 seconds.2) Starting
The plugs remain supplied while the starter is
being activated.
3) "Postheating" while the engine is running
During this phase the plugs are supplied
continuously according to coolant temperature.

Heater plugs
The resistance of a heater plug is 0.6 Ω.
Plugs may be removed without having to open the
high pressure circuit.
REMOVAL
Unclip the plug connector.
Clean the plug exterior to avoid any dirt entering the
cylinder.
Undo and then remove the plugs.
To undo the plug on cylinder 4 use a 10 mm long radio
socket attached to a universal joint. Once the plug is
loosened use a pipe socket to unscrew it completely.
REFITTING
Proceed in the reverse order to removal.TIGHTENING TORQUES (in daN.m)

119 COOLING SYSTEM
Filling and bleeding
There is no heater matrix water control valve.
Water flow is continuous in the heater matrix, which
contributes to the cooling of the engine.
FILLING
It is essential to open the bleed screw on the
cylinder head coolant pipe housing outlet.
Fill the circuit through the expansion bottle opening.
Close the bleed screw as soon as the fluid runs out in
a continuous jet.
Start the engine (2500 rpm).
Adjust the level by overflow for a period of about
4 minutes.
Tighten the expansion bottle cap.
BLEEDING
Let the engine run for 20 minutes at 2500 rpm, until
the engine cooling fan operates (time required for
automatic degassing).
Check the liquid level is at the "Maximum" marker.
DO NOT OPEN THE BLEED SCREW(S) WITH THE
ENGINE RUNNING.
REFIT THE EXPANSION BOTTLE CAP WHILE THE
ENGINE IS WARM.
